' Applicatio'n mammar 4,1919; Serial miamasa To all w/wmitmay concern;

Be t known thatI, WALTER B.,W001 J,'a citizen of the Unltedfitatcs of Amer ca, and a resident vo'l. Downmgtown, Chester county, and State of Pennsylvania, have invented certain new and useful Improvements {1n heals, of Wl11Gh tl18ilTOllOWlllglS aspemhca- 'tlon, reference being hadto thetaccon pany 111g drawings, forminga part'thereofr My invention relatestoflthatclassbf devices WlllChtBG1186(1fOlSQtllllllgtthfi locks of car doors, but my particularidevice is also applicable to seal boxes, packages, or bundles The object ofmy inventionis to provide a simple and inexpensive 'devicewhich ,is easily applied and which-cannot berem'oved without first breakingria part thereof, and this cannot be donewithout leavingytraees Which may be easily. detected. Thus, it is adapted to serve as. a positive indication 10ft tampering if the .sealeddoor, package .or bundle has been opened Without authority.

In order thatmy. invention maybethoroughly understood I will now proceed -;t0' describe the "same in the following specification, and will then point out thenoyel features thereof in] appended. claims. 7

The. locking tool. comprises two jaws 30 -3 1 whiohqare pivoted. together at .32.- The upper end of the jaw: 30 forms a Qrcetangular pocket ,ofsuch size; and shape ttS1;;. 95

tou'eceive a corner'of the block 10 andto position this blockin relation tothe other jaw 31. On: thisgother jaw ;is a plunger 34 V which, when albloeklis inserted and posijf tio 'ied inithe pocket 33 ofthe jaw 30.,Wi ll, beina'txial alinementwith the hole 14.

In Fig. 1, the car door look shownt co nprlsesa hasp 40, a staple 41, and ashding .bolt afltlirough which near its lower end, is atransyerse slot 4L3. r rBefore describ ng speclhcally the con struction. of. the device shown in Figs .7 and 8;:Iiw1ll describethe manner in wh ch this I device used. .Theend of the flatmetallic strip-20 ispassed through the partto be sealed, suchdor example; as through the slot fli thro'ugh; the bolt 42, and; is then passed down through IllfijllOlG 12 until it projects through the block 10'. The parts will then assume; the. relative positions in .whieh they ing member 15".

are shown in Fig. 3. After this the clamp ing tool is applied and by moving the aws 30 and 31 together, the plunger 34 will push the locking pin 22 through both parts of the flexible metallic strip 20 and into the osition in which it is shown in Fig. 2. fter this, it is impossible to release the bolt 43 without first breaking some part of the seal. This is because the in 22 is absolutely inaccessible. The slot 11 and the depressed upper end 17 of the back of the locking member, are arranged so that it is impossible for anyone to break by bending the parts of the strip 20 where they leave the lockin memberi 15, without showing clearly the roken en s.

In the form of the device which is shown in, Fig. 7 the block 10 is of the same form.

and construction as that previously described and the locking member 15 is also thesame, so that atleast one of the holes 18 therein is threaded. With this device the flexible metallic strip is applied to the device to. be sealed in the same manner as that which has been described, after which a pin 50, the end of which is threaded,is screwed into the threaded hole 18 until the metal of the strip 21 is either punctured yoryis so depressed that it cannot be removed from the look. No s ecial tool is required for applying this orm. of seal but the'pin is made long enough to have'its handle 51project outside of the block and by means of this handle the pin is screwed into the lock- ,verse out 52 is made in the shank of the pin which reduces the strengthof the device at that particular point so that after it has "I have illustratedand described several forms of my'invention for: the purpose of showing that I do not wish to .limit myself to any specific form of construction, and in fact I intend no limitations other than those I imposed by the appended claims.

What I claim 1s: i 1. A seal comprising a block, a lockin member ofdifl'erent material than that of the block therein having sides closely dis posed, at least one of which is provided with a perforation, a flat flexible strip extending from thelocking member and having a free end adapted to be inserted in the block near the perforated side of the locking member,

across the perforation therein,said blockbe ing provided with a hole in alinement with "cum 0! m: m may we autism, nv tiehth hbll, bysuraiiii {is "stimulants? of fatezit'i} perforations, a fiat flexible stri Between the handle and y the threaded end of the locking pin, a trans:
